1. A membrane eyelet for deployment in an opening in a tissue membrane comprising:
- a waist section having a first end, a second end, and a plurality of struts extending between the first end and the second end for engaging an interior edge in an opening created in a tissue membrane;
a first anchor section coupled to the waist section;
a second anchor section coupled to the waist section;
the first anchor section, and the second anchor section each having a waist end that is coupled to the waist section and a free end and a long axis of the eyelet extending therebetween;
the membrane eyelet having a delivery configuration in which the entirety of the membrane eyelet can be passed through the opening in a tissue membrane; and
the membrane eyelet having a deployment configuration in which the waist section is positioned in the opening such that the struts can engage the interior edge of the opening, and each of the anchor sections are outside of the opening and on opposite sides of the tissue membrane.

Abstract
A structure and method for deploying an eyelet in a membrane, where the eyelet includes: a waist section; a first anchor section coupled to and flared from the waist section; and a second anchor section coupled to and flared from the waist section. The eyelet is deployed such that the waist section is located within a membrane opening of the membrane thus keeping the membrane opening open. Further, the membrane is sandwiched between the first and second anchor sections thus anchoring the eyelet to the membrane.

12. A structure comprising:
-
a membrane eyelet configured for insertion in an opening in a tissue membrane in the body of a patient, the membrane eyelet further comprising;
a waist section having a plurality of contact points for engaging an interior edge of an opening in a tissue membrane;
a first anchor section coupled to the waist section;
a second anchor section coupled the waist;
the waist section, the first anchor section, and the second anchor section each having a long axis;
the first anchor section, and the second anchor section each having a waist end that is coupled to the waist section and a free end;
the membrane eyelet having a delivery configuration in which each of the anchor sections have a radial delivery diameter and the long axis of each of the anchor sections is parallel to the long axis of the waist section; and
the membrane eyelet having a deployment configuration in which the free end of each of the anchor sections is flared radially outward such that the free ends have a radial deployment diameter that is greater than the radial delivery diameter, the free end of each of the anchor sections extends at an angle from the long axis of the waist section and the waist section has a smaller radial diameter than the radial deployment diameter of the free ends of the anchor section, such that when the structure is inserted in an opening in a tissue membrane in the body of a patient the anchor sections are outside of the opening and each is on a different side of the tissue membrane, the tissue membrane is secured between the anchor sections and the contact points on the waist section are positioned to engage an inner edge of the opening in the tissue membrane. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
